Description

本発明は、例えば、各種建築物の建築現場や補修現場、土木作業現場等で構築される仮設足場を構成する仮設足場用部材に関し、特に仮設足場の本体部分から水平方向に張り出すように張り出し仮設足場を構築する場合に使用される仮設足場用部材に関する。   The present invention relates to, for example, a temporary scaffolding member constituting a temporary scaffold constructed at a construction site or a repair site of various buildings, a civil engineering work site or the like, and in particular, overhangs so as to horizontally project from the main body part of the temporary scaffold. The present invention relates to a temporary scaffolding member used when constructing a temporary scaffolding.

一般に、各種建築物の建築現場や補修現場、土木作業現場等では、作業を行うための仮設足場が構築される。仮設足場は、複数の支柱部材、支柱部材を連結する布材やブレース材、梁部材、床板等を組み合わせて構築されている(例えば、特許文献1〜5参照)。   Generally, temporary scaffoldings for working are constructed at construction sites, repair sites, civil engineering work sites, etc. of various buildings. The temporary scaffold is constructed by combining a plurality of support members, a cloth material connecting the support members, a brace material, a beam member, a floor plate, and the like (see, for example, Patent Documents 1 to 5).

特許文献4の仮設足場は、梁部材の長手方向と交差する方向に延び、梁部材から前後方向に突出するように設けられた複数本の根太部材と、複数本の根太部材に渡って掛け渡される床板とを有している。   The temporary scaffold of Patent Document 4 extends over a plurality of joist members provided to extend in a direction intersecting with the longitudinal direction of the beam member and protruding from the joist members in the front-rear direction, and spanning over the plurality joist members And a floor plate to be

特許文献5には、仮設足場本体から水平方向に張り出すように設置される張り出しブラケットが開示されている。張り出しブラケットは、水平部材と、水平部材の基端部に設けられたクサビと、水平部材の先端部に設けられたホゾと、水平部材のホゾ側からクサビ側に向けて下降傾斜した補強材とを備えている。ホゾには上下方向に延びる分岐用支柱が結合されている。クサビが結合される支柱と分岐用支柱と繋ぐように手すりが設けられている。   Patent Document 5 discloses an overhang bracket installed so as to project horizontally from a temporary scaffold main body.

ところで、例えば図6に示す高架橋100は、レール等が敷設される橋桁部101と、橋桁部101の側部に設けられた側壁部102とを備えており、この高架橋100を補修等する場合には、一般的に、同図に示すように橋桁部101の下方に仮設足場1を構築することになる。   By the way, for example, the viaduct 100 shown in FIG. 6 includes a bridge girder portion 101 on which rails and the like are laid and a side wall portion 102 provided on the side of the bridge girder portion 101. In general, a temporary scaffold 1 will be constructed below the bridge girder part 101 as shown in the figure.

仮設足場1を橋桁部101の下方に構築することで、橋桁部101の下面の補修等は可能であるが、側壁部102の外面の補修等が問題になる。すなわち、仮設足場1の幅を基礎部分から上部に亘って全体として拡張し、側壁部102の外面に達するような大型の仮設足場にすることで、側壁部102の外面に対する補修等が行えるようになるが、そのような大型の仮設足場を構築するためには多くの資材が必要になるとともに、工数も増大してしまう。また、現場の状態によっては仮設足場の基礎部分の幅を拡張できない場合も想定される。よって、側壁部102については、吊り下げ式の仮設足場等を別途構築しなければならなかった。   By constructing the temporary scaffold 1 below the bridge girder part 101, although repair or the like of the lower surface of the bridge girder part 101 is possible, repair of the outer surface of the side wall part 102 or the like becomes a problem. That is, by making the width of the temporary scaffold 1 as a whole from the base portion to the upper part into a large temporary scaffold that reaches the outer surface of the side wall portion 102, the outer surface of the side wall portion 102 can be repaired. However, in order to construct such a large temporary scaffold, a lot of materials are required, and the number of man-hours also increases. In addition, depending on the condition of the site, it may be assumed that the width of the base portion of the temporary scaffold can not be expanded. Therefore, for the side wall portion 102, a suspended temporary scaffold or the like had to be separately constructed.

ここで、特許文献4では、梁部材から前後方向に突出するように設けられた複数本の根太部材に渡って床板を掛け渡すようにしており、これによって仮設足場本体から水平方向に張り出す作業床を得ることができるようになっている。しかしながら、高架橋100の側壁部102の高さが高い場合には、単に作業床が水平方向に張り出しているだけでは高さが足りないという問題がある。   Here, in Patent Document 4, the floor plate is bridged over a plurality of joist members provided so as to project from the beam member in the front-rear direction, whereby the work of projecting horizontally from the temporary scaffold main body is performed. It is possible to get a floor. However, in the case where the height of the side wall portion 102 of the viaduct 100 is high, there is a problem that the height is not sufficient simply by projecting the working floor in the horizontal direction.

また、特許文献5では、張り出しブラケットを設けることで、仮設足場本体から水平方向に張り出す作業床を得ることができると考えられる。しかしながら、この特許文献5も特許文献4と同様に単に作業床が水平方向に張り出しているだけなので、高さの問題がある。   Moreover, in patent document 5, it is thought that the work floor projected horizontally from a temporary scaffold main body can be obtained by providing an overhang bracket. However, Patent Document 5 also has a problem of height because the work floor merely extends horizontally in the same manner as Patent Document 4.

上述したような問題は高架橋100だけのものではなく、他の建築物の建築現場や補修現場、土木作業現場等でも起こり得る。   The problems as described above are not limited to the viaduct 100, and may occur in other construction sites, repair sites, civil engineering work sites, and the like.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、仮設足場本体から水平方向に張り出した作業床を高いところにも形成できるようにすることにある。   This invention is made in view of this point, The place made as the objective is enabling it to form in the high place also the work floor which extended in the horizontal direction from the temporary scaffold main body.

上記目的を達成するために、本発明では、仮設足場本体から水平方向に延びるように設けられる横部材の先端部に、作業床となる床板を支持する支柱を連結可能にした。   In order to achieve the above object, in the present invention, a support for supporting a floor plate serving as a work floor can be connected to the tip of a horizontal member provided to extend horizontally from a temporary scaffold main body.

(Configuration of temporary scaffolding member 10)
As shown in FIGS. 1 and 2, the temporary scaffolding member 10 includes a lateral member 11, a connecting member (connecting portion) 14, a first reinforcing member 15, a lower fixed tube member 16, and a lower movable tube. A member 17, a male screw member 18, a second reinforcing member 20, a clamp member 21, a first longitudinal member 22 and a second longitudinal member 23 are provided.

図5等に示すように、横部材11は、仮設足場本体2を構成する本体側支柱4に連結され、該仮設足場本体2から水平方向に延びるように設けられる部材である。すなわち、横部材11は、本体側支柱4に連結されて仮設足場本体2から水平方向に突出するように延びる固定部材12と、該固定部材12に対して水平方向に移動可能に取り付けられ、該固定部材12の先端部から突出する可動部材13とを備えている。   As shown in FIG. 5 etc., the lateral member 11 is a member that is connected to the main body side support 4 that constitutes the temporary scaffold main body 2 and extends from the temporary scaffold main body 2 in the horizontal direction. That is, the horizontal member 11 is attached to the fixing member 12 so as to be movable in the horizontal direction with respect to the fixing member 12, the fixing member 12 being connected to the main body side column 4 and extending horizontally from the temporary scaffold main body 2. And a movable member 13 projecting from the tip of the fixed member 12.

固定部材12は、仮設足場本体2から水平方向に延びる鋼管からなる管部材で構成されている。固定部材12の先端部(図1における右端部)の下側には、ネジ孔を有するナット12aが下方へ突出するように固定されている。このナット12aのネジ孔には、雄ネジ部材18が螺合するようになっている。固定部材12の先端部の周壁部には、ナット12aのネジ孔と連通する貫通孔(図示せず)が該周壁部を貫通するように形成されており、ナット12aのネジ孔に螺合した雄ネジ部材18の先端部が貫通孔を通って固定部材12の内部へ突出可能に構成されている。   The fixing member 12 is formed of a pipe member made of a steel pipe extending in the horizontal direction from the temporary scaffold main body 2. A nut 12a having a screw hole is fixed to the lower side of the tip end portion (right end portion in FIG. 1) of the fixing member 12 so as to project downward. A male screw member 18 is screwed into the screw hole of the nut 12a. A through hole (not shown) communicating with the screw hole of the nut 12a is formed in the peripheral wall of the distal end of the fixing member 12 so as to penetrate the peripheral wall and screwed into the screw hole of the nut 12a The tip end of the male screw member 18 is configured to be able to project into the interior of the fixing member 12 through the through hole.

固定部材12の基端部(図1における左端部)における下側には、クサビ12bが下方へ突出するように固定されている。このクサビ12bは、本体側支柱4のクサビ差し込み部4aに上方から差し込まれた状態で係合するようになっている。また、固定部材12におけるナット12aとクサビ12bとの間には、金属製の板材からなるブラケット12cが下方へ突出するように設けられている。ブラケット12cは、クサビ12bに接近して設けられている。   A wedge 12b is fixed to the lower side of the proximal end (left end in FIG. 1) of the fixing member 12 so as to project downward. The wedge 12 b is engaged with the wedge insertion portion 4 a of the main body side support 4 while being inserted from above. Further, a bracket 12c made of a metal plate material is provided between the nut 12a and the wedge 12b in the fixing member 12 so as to project downward. The bracket 12c is provided close to the wedge 12b.

可動部材13は、鋼管からなる管部材で構成されている。可動部材13の外径は、固定部材12の内径よりも小さく設定されており、固定部材12の内部に差し込むことが可能に形成されている。可動部材13の長さは、固定部材12の長さよりも短く設定されている。可動部材13は、固定部材12に差し込んだ状態で該固定部材12の中心線方向(水平方向)に相対的に移動させることができるようになっており、図1に示すように可動部材13を進出させた状態から、図2に示すように可動部材13を後退させた状態、また可動部材13を後退させた状態から、進出させた状態にすることができる。   The movable member 13 is constituted by a pipe member made of a steel pipe. The outer diameter of the movable member 13 is set to be smaller than the inner diameter of the fixed member 12 and can be inserted into the fixed member 12. The length of the movable member 13 is set shorter than the length of the fixed member 12. The movable member 13 can be relatively moved in the center line direction (horizontal direction) of the fixed member 12 in a state of being inserted into the fixed member 12, and as shown in FIG. From the advanced state, as shown in FIG. 2, the movable member 13 can be moved backward, or the movable member 13 can be moved backward from the retracted state.

可動部材13は、進出させた状態と後退させた状態との間の任意の位置で停止させることができる。図1に示す可動部材13を進出させた状態では、横部材11の長さが1500mm〜2000mmの間となるように、固定部材12及び可動部材13の長さを設定することができる。また、図2に示す可動部材13を後退させた状態では、横部材11の長さが800mm〜1500mmの間となるように、固定部材12及び可動部材13の長さを設定することができる。   The movable member 13 can be stopped at any position between the advanced state and the retracted state. In the state in which the movable member 13 shown in FIG. 1 is advanced, the lengths of the fixed member 12 and the movable member 13 can be set such that the length of the horizontal member 11 is between 1500 mm and 2000 mm. Further, in a state in which the movable member 13 shown in FIG. 2 is retracted, the lengths of the fixed member 12 and the movable member 13 can be set so that the length of the horizontal member 11 is between 800 mm and 1500 mm.

雄ネジ部材18は、可動部材13が固定部材12に対して水平方向に移動するのを阻止するための阻止部材である。この雄ネジ部材18は、固定部材12に固定されたナット12aのネジ孔に螺合させて時計回りに回転させると固定部材12の内部へ進出する一方、反時計周りに回転させると後退する。つまり、雄ネジ部材18は、固定部材12に設けられたネジ孔に螺合することによって進退動作する。   The male screw member 18 is a blocking member for blocking the movable member 13 from moving in the horizontal direction with respect to the fixed member 12. The male screw member 18 is screwed into the screw hole of the nut 12a fixed to the fixing member 12 and is rotated clockwise, and advances into the inside of the fixing member 12, while it is retracted when it is rotated counterclockwise. That is, the male screw member 18 advances and retracts by being screwed into a screw hole provided in the fixing member 12.

雄ネジ部材18が進出すると、固定部材12の貫通孔を通って固定部材12の内部へ突出するので、雄ネジ部18の先端部が、固定部材12の内部に差し込まれている可動部材13の外面に当接し、更に雄ネジ部材18を締め込むことで可動部材13の水平方向の移動を雄ネジ部18によって阻止することができる。一方、雄ネジ部材18が後退した状態では、雄ネジ部18の先端部が、固定部材12の内部に差し込まれている可動部材13の外面から離れるので、該可動部材13の水平方向の移動を許容することになる。従って、雄ネジ部18を緩めることで可動部材13を固定部材12に対して水平方向に移動させて横部材11の長さを無段階に変更することができ、横部材11が所望の長さになった時に雄ネジ部18を締め込むことで可動部材13が固定部材12に固定されて横部材11の長さが所望の長さから変化しないように、長さを維持することができる。   When the male screw member 18 is advanced, the male screw member 18 protrudes through the through hole of the fixed member 12 into the inside of the fixed member 12, so that the tip of the male screw 18 is inserted into the inside of the fixed member 12. The horizontal movement of the movable member 13 can be blocked by the male screw 18 by abutting on the outer surface and further tightening the male screw 18. On the other hand, in the state where the male screw member 18 is retracted, the distal end of the male screw 18 separates from the outer surface of the movable member 13 inserted into the inside of the fixed member 12. It will be acceptable. Therefore, by loosening the male screw portion 18, the movable member 13 can be moved horizontally with respect to the fixed member 12 to change the length of the cross member 11 steplessly, and the cross member 11 has a desired length. By tightening the male screw portion 18 when it comes to a fixed length, the movable member 13 can be fixed to the fixed member 12 and the length can be maintained so that the length of the cross member 11 does not change from the desired length.

固定部材12のブラケット12cの下部には、上下方向に延びる傾斜部材24の上端部が連結されている。傾斜部材24の下部は、固定部材12の基端部から下方に離れている。この傾斜部材24の下部には、クランプ部材25が連結されている。クランプ部材25は、仮設足場本体2の本体側支柱4を径方向に挟持する(クランプする)ように構成された周知の部材である。   The lower end of the bracket 12 c of the fixing member 12 is connected to an upper end portion of an inclined member 24 extending in the vertical direction. The lower portion of the inclined member 24 is spaced downward from the proximal end of the fixing member 12. The clamp member 25 is connected to the lower portion of the inclined member 24. The clamp member 25 is a known member configured to clamp (clamp) the main body side support column 4 of the temporary scaffold main body 2 in the radial direction.

連結部材14は、横部材11の先端部、即ち、可動部材13における固定部材12の先端部から突出する部分に固定されている。連結部材14には、図4に示すように作業床5となる床板5aを横部材11から上方に離して支持可能な側部支柱6の下部が連結される。連結部材14は、上下方向に延びる鋼管からなる管部材で構成されている。連結部材14の内径は、側部支柱6の外径よりも若干小さく設定されており、側部支柱6の下部を連結部材14に差し込むことにより、側部支柱6の下部を連結部材14に連結することができるようになっている。   The connecting member 14 is fixed to the end of the cross member 11, that is, the portion of the movable member 13 that protrudes from the end of the fixed member 12. As shown in FIG. 4, the lower portion of the side support 6 capable of supporting the floor plate 5 a serving as the work floor 5 upward from the cross member 11 is connected to the connecting member 14. The connection member 14 is formed of a pipe member made of a steel pipe extending in the vertical direction. The inner diameter of the connecting member 14 is set to be slightly smaller than the outer diameter of the side support 6, and the lower portion of the side support 6 is connected to the connecting member 14 by inserting the lower portion of the side support 6 into the connecting member 14. It can be done.

連結部材14の上部には、上側接続管部14aが横部材11側へ向けて水平方向に突出するように固定されている。上側接続管部14aの内径は、可動部材13の外径よりも若干大きく設定されており、可動部材13の先端部を上側接続管部14aに差し込むことができるようになっている。可動部材13の先端部は、上側接続管部14aに差し込まれた状態で溶接や締結部材等によって固定されている。また、連結部材14における上側接続管部14aから下方に離れた部位には、下側接続管部14bが上側接続管部14aと同方向に突出するように固定されている。さらに、連結部材14の下部には、突出板部14cが下方へ突出するように設けられている。   An upper connection pipe portion 14 a is fixed to an upper portion of the connection member 14 so as to horizontally project toward the cross member 11 side. The inner diameter of the upper connection pipe portion 14a is set to be slightly larger than the outer diameter of the movable member 13, and the tip end portion of the movable member 13 can be inserted into the upper connection pipe portion 14a. The distal end portion of the movable member 13 is fixed by welding, a fastening member or the like in a state of being inserted into the upper connection pipe portion 14a. Further, the lower connection pipe portion 14 b is fixed to a portion of the connection member 14 which is separated downward from the upper connection pipe portion 14 a so as to project in the same direction as the upper connection pipe portion 14 a. Further, a projecting plate portion 14 c is provided at the lower part of the connecting member 14 so as to project downward.

第1補強部材15は上下方向に延びており、上側へ行くほど固定部材12の先端部に近づくように傾斜している。第1補強部材15は鋼管で構成されている。第1補強部材15の上部は、略鉛直に延びる鉛直部15aで構成されており、この鉛直部15aも鋼管である。鉛直部15aの上端部は、固定部材12の先端側においてナット12aよりも基端寄りの部位に固定されている。これにより、第1補強部材15の上端部が固定部材12に固定されることになる。   The first reinforcing member 15 extends in the vertical direction, and is inclined so as to approach the tip of the fixing member 12 as it goes upward. The first reinforcing member 15 is formed of a steel pipe. The upper portion of the first reinforcing member 15 is formed of a vertical portion 15a extending substantially vertically, and the vertical portion 15a is also a steel pipe. The upper end portion of the vertical portion 15 a is fixed at a position closer to the base end than the nut 12 a on the tip end side of the fixing member 12. As a result, the upper end portion of the first reinforcing member 15 is fixed to the fixing member 12.

第1補強部材15の下端部は、本体側支柱4における固定部材12の連結部位よりも下方の部位に連結されるようになっている。すなわち、第1補強部材15の下端部は固定部材12の基端部よりも下方に位置しており、この第1補強部材15の下端部には連結板部15bが設けられている。連結板部15bは上下方向に延びていて、その上端部が第1補強部材15の下端部に対して溶接等の固定方法によって固定されている。連結板部15bの下部には、本体側支柱4のクサビ差し込み部4aに差し込まれるクサビ15dが固定されている。クサビ15dと、クサビ12bとは、上下方向に延びる同一直線上に位置するように配置される。また、連結板部15bの上部には、本体側支柱4に対して側方から当接する当接部15cが設けられている。   The lower end portion of the first reinforcing member 15 is connected to a portion below the connection portion of the fixing member 12 in the main body side support 4. That is, the lower end portion of the first reinforcing member 15 is located below the base end portion of the fixing member 12, and the connecting plate portion 15 b is provided at the lower end portion of the first reinforcing member 15. The connecting plate portion 15 b extends in the vertical direction, and the upper end portion thereof is fixed to the lower end portion of the first reinforcing member 15 by a fixing method such as welding. The wedge 15 d to be inserted into the wedge insertion portion 4 a of the main body side support 4 is fixed to the lower portion of the connection plate portion 15 b. The wedge 15 d and the wedge 12 b are disposed on the same straight line extending in the vertical direction. Further, on the upper portion of the connection plate portion 15b, a contact portion 15c that contacts the main body side support 4 from the side is provided.

第1補強部材15には、固定部材12よりも下方に位置付けられるとともに、該固定部材12と略平行に延びる下側固定管部材16が固定されている。下側固定管部材16は、鋼管で構成されている。下側固定管部材16の中心線方向中央部よりも先端側(図1における右側)寄りの部位が、第1補強部材15における鉛直部15aの下端部に固定されている。   A lower fixed tube member 16 which is positioned below the fixed member 12 and extends substantially in parallel with the fixed member 12 is fixed to the first reinforcing member 15. The lower fixed pipe member 16 is formed of a steel pipe. A portion closer to the tip end side (right side in FIG. 1) than the central portion of the lower fixed tube member 16 in the center line direction is fixed to the lower end portion of the vertical portion 15 a of the first reinforcing member 15.

下側固定管部材16には、水平方向に延びる鋼管からなる下側可動管部材17が取り付けられている。下側可動管部材17の外径は、下側固定管部材16の内径よりも若干小さく設定されており、下側可動管部材17を下側固定管部材16に差し込んだ状態で中心線方向に相対的に移動させることが可能になっている。つまり、下側可動管部材17は、下側固定管部材16に対して水平方向に移動可能に取り付けられている。   A lower movable pipe member 17 made of a steel pipe extending in the horizontal direction is attached to the lower fixed pipe member 16. The outer diameter of the lower movable tube member 17 is set to be slightly smaller than the inner diameter of the lower fixed tube member 16, and in the direction of the center line with the lower movable tube member 17 inserted in the lower fixed tube member 16. It is possible to move relatively. That is, the lower movable pipe member 17 is mounted movably in the horizontal direction with respect to the lower fixed pipe member 16.

下側可動管部材17の長さは、下側固定管部材16に差し込んだ状態で該下側固定管部材16の先端部から突出するように設定されている。下側可動管部材17における下側固定管部材16の先端部から突出する部分に連結部材14が固定されている。すなわち、下側可動管部材17の外径は、連結部材14の下側接続管部14bの内径よりも若干小さく設定されており、下側可動管部材17における下側固定管部材16の先端部から突出する部分を連結部材14の下側接続管部14bに差し込むことができるようになっている。下側可動管部材17における下側固定管部材16の先端部から突出する部分は、下側接続管部14bに差し込まれた状態で溶接や締結部材等によって固定されている。従って、連結部材14における可動部材13の固定部位よりも下方の部位に下側可動管部材17が固定されることになる。   The length of the lower movable tube member 17 is set to project from the tip of the lower fixed tube member 16 in a state of being inserted into the lower fixed tube member 16. The connecting member 14 is fixed to a portion of the lower movable pipe member 17 that protrudes from the tip of the lower fixed pipe member 16. That is, the outer diameter of the lower movable pipe member 17 is set to be slightly smaller than the inner diameter of the lower connection pipe portion 14 b of the connection member 14, and the tip of the lower fixed pipe member 16 in the lower movable pipe member 17 The part which protrudes from can be inserted in the lower connection pipe part 14b of the connection member 14. As shown in FIG. The portion of the lower movable pipe member 17 that protrudes from the tip end of the lower fixed pipe member 16 is fixed by welding, a fastening member, or the like in a state of being inserted into the lower connection pipe portion 14b. Therefore, the lower movable tube member 17 is fixed to a portion of the connecting member 14 below the fixed portion of the movable member 13.

第2補強部材20は、上下方向に延びる金属製の棒材や管材等からなるものである。第2補強部材20の上端部は、連結部材14の突出板部14cに対して水平方向に延びる軸20a周りに揺動可能に連結されている。軸20aは、第2補強部材20の上端部を支持し、かつ、第2補強部材20の下端部が第1補強部材15に接離するように、第2補強部材20を揺動させる揺動軸となる部材である。   The second reinforcing member 20 is made of a metal bar or pipe extending in the vertical direction. The upper end portion of the second reinforcing member 20 is swingably connected around an axis 20 a extending in the horizontal direction with respect to the protruding plate portion 14 c of the connecting member 14. The shaft 20a supports the upper end portion of the second reinforcing member 20, and swings the second reinforcing member 20 so that the lower end portion of the second reinforcing member 20 contacts and separates from the first reinforcing member 15. It is a member which becomes an axis.

第2補強部材20の下端部には、第1補強部材15をクランプするためのクランプ部材21が水平方向に延びる軸20b周りに揺動可能に連結されている。軸20bの延びる方向は軸20aの延びる方向と一致している。クランプ部材21は、第1補強部材15を径方向に挟持する(クランプする)ように構成された周知の部材である。   At the lower end portion of the second reinforcing member 20, a clamp member 21 for clamping the first reinforcing member 15 is swingably connected around an axis 20b extending in the horizontal direction. The extending direction of the shaft 20b coincides with the extending direction of the shaft 20a. The clamp member 21 is a known member configured to clamp (clamp) the first reinforcing member 15 in the radial direction.

図1に示す可動部材13を進出させた状態では、可動部材13に下側可動管部材17が連結部材14を介して連結されているので、下側可動管部材17も進出することになる。また、このとき、第2補強部材20の上端部が可動部材13に連結部材14を介して連結されているので、第2補強部材20の上端部も同様に進出することになる。第2補強部材20の上端部が進出すると、第2補強部材20が揺動して該第2補強部材20の下端部が上昇することになる。この上昇位置でクランプ部材21により第1補強部材15をクランプすると、第2補強部材20により連結部材14を下方から支持することができるとともに、連結部材14の傾きを抑制することができる。また、第2補強部材20の水平面に対する傾斜角度は、第1補強部材15の水平面に対する傾斜角度よりも緩やかになっている。   In the state in which the movable member 13 shown in FIG. 1 is advanced, since the lower movable pipe member 17 is connected to the movable member 13 via the connecting member 14, the lower movable pipe member 17 is also advanced. At this time, since the upper end portion of the second reinforcing member 20 is connected to the movable member 13 via the connecting member 14, the upper end portion of the second reinforcing member 20 also advances. When the upper end portion of the second reinforcing member 20 advances, the second reinforcing member 20 swings and the lower end portion of the second reinforcing member 20 is lifted. When the first reinforcing member 15 is clamped by the clamp member 21 at the raised position, the connecting member 14 can be supported from below by the second reinforcing member 20, and the inclination of the connecting member 14 can be suppressed. Further, the inclination angle of the second reinforcing member 20 with respect to the horizontal plane is gentler than the inclination angle of the first reinforcing member 15 with respect to the horizontal plane.

図2に示す可動部材13を後退させた状態では、下側可動管部材17も後退し、第2補強部材20の上端部も後退する。第2補強部材20の上端部が後退すると、第2補強部材20が揺動して該第2補強部材20の下端部が下降することになる。この下降位置でクランプ部材21により第1補強部材15をクランプすると、第2補強部材20により連結部材14を下方から支持することができるとともに、連結部材14の傾きを抑制することができる。クランプ部材21による第1補強部材15のクランプ位置は、第2補強部材20の揺動角度に応じて無段階で変更することができる。   In the state where the movable member 13 shown in FIG. 2 is retracted, the lower movable pipe member 17 is also retracted, and the upper end portion of the second reinforcing member 20 is also retracted. When the upper end portion of the second reinforcing member 20 retracts, the second reinforcing member 20 swings and the lower end portion of the second reinforcing member 20 is lowered. When the first reinforcing member 15 is clamped by the clamp member 21 at the lowered position, the connecting member 14 can be supported from below by the second reinforcing member 20, and the inclination of the connecting member 14 can be suppressed. The clamp position of the first reinforcing member 15 by the clamp member 21 can be changed steplessly according to the swing angle of the second reinforcing member 20.

第1縦部材22は上下方向に延びる金属製の棒材や管材等からなるものである。第1縦部材22の上端部は、固定部材12における鉛直部15aの固定部位よりも基端寄りの部位に固定されている。第1縦部材22の下端部は、第1補強部材15におけるクランプ部材21によるクランプ位置(上昇端位置)よりも上側の部位に固定されている。また、第1縦部材22の上下方向中間部には、下側固定管部材16の基端部が固定されている。従って、第1縦部材22によって固定部材12と第1補強部材15を連結することができるとともに、固定部材12と下側固定管部材16、下側固定管部材16と第1補強部材15を連結することもできる。   The first vertical member 22 is made of a metal bar or pipe extending in the vertical direction. The upper end portion of the first vertical member 22 is fixed to a portion closer to the proximal end than the fixing portion of the vertical portion 15 a in the fixing member 12. The lower end portion of the first vertical member 22 is fixed at a position above the clamping position (rising end position) of the first reinforcing member 15 by the clamp member 21. Further, a base end portion of the lower fixed tube member 16 is fixed to a vertically middle portion of the first vertical member 22. Therefore, while being able to connect fixed member 12 and the 1st reinforcement member 15 by the 1st vertical member 22, fixed member 12 and lower fixed tube member 16, lower fixed tube member 16 and 1st reinforcement member 15 are connected. You can also

第2縦部材23は上下方向に延びる金属製の棒材や管材等からなるものである。第2縦部材23の上端部は、固定部材12における第1縦部材22の固定部位よりも基端寄りの部位に固定されている。第2縦部材23の下端部は、第1補強部材15におけるクランプ部材21によるクランプ位置(図2に示す下降端位置)よりも下側の部位に固定されている。従って、第2縦部材23によって固定部材12と第1補強部材15を連結することができる。また、第1補強部材15におけるクランプ部材21によるクランプ位置は、上昇端位置であっても下降端位置であっても、第1縦部材22と第2縦部材23との間に設定される。   The second vertical member 23 is made of a metal rod or pipe extending in the vertical direction. The upper end portion of the second vertical member 23 is fixed to a portion closer to the proximal end than the fixing portion of the first vertical member 22 in the fixing member 12. The lower end portion of the second vertical member 23 is fixed at a lower position than the clamp position (the lowering end position shown in FIG. 2) by the clamp member 21 in the first reinforcing member 15. Therefore, the fixing member 12 and the first reinforcing member 15 can be connected by the second vertical member 23. Further, the clamp position of the first reinforcement member 15 by the clamp member 21 is set between the first longitudinal member 22 and the second longitudinal member 23 regardless of whether it is the rising end position or the falling end position.

(仮設足場の構築)
次に、上記のように構成された仮設足場用部材10を使用して仮設足場を構築する場合について説明する。まず、図6に示すように橋桁部101の下方に仮設足場本体2を構築する。また、実施形態に係る仮設足場用部材10の連結部材14の水平方向の位置を所望の位置にしておく。このとき、雄ネジ部材18を緩めておくとともに、クランプ部材21を非クランプ状態としておく。これにより、可動部材13及び下側可動管部材17を水平方向に移動させることができるとともに、可動部材13及び下側可動管部材17の水平方向の移動に連動させて第2補強部材20を揺動させることができる。連結部材14の水平方向の位置を所望の位置にした後、雄ネジ部材18を締め込むとともに、クランプ部材21をクランプ状態にすることで連結部材14が固定される。連結部材14の位置は、作業床5を、高架橋100の側壁部102から外側に離した所に形成することができるように設定する。
(Construction of temporary scaffolding)
Next, the case where a temporary scaffold is constructed | assembled using the member 10 for temporary scaffolds comprised as mentioned above is demonstrated. First, as shown in FIG. 6, the temporary scaffold main body 2 is constructed below the bridge girder part 101. Further, the horizontal position of the connection member 14 of the temporary scaffolding member 10 according to the embodiment is set to a desired position. At this time, the male screw member 18 is loosened and the clamp member 21 is unclamped. Thereby, the movable member 13 and the lower movable pipe member 17 can be moved in the horizontal direction, and the second reinforcing member 20 is shaken in conjunction with the horizontal movement of the movable member 13 and the lower movable pipe member 17. It can be moved. After setting the horizontal position of the connecting member 14 to a desired position, the connecting member 14 is fixed by tightening the male screw member 18 and putting the clamp member 21 in a clamping state. The position of the connecting member 14 is set such that the working floor 5 can be formed at a position away from the side wall portion 102 of the viaduct 100.

その後、図3に示すように、仮設足場本体2の上部における幅方向両側にそれぞれ実施形態に係る仮設足場用部材10を連結する。このとき、仮設足場用部材10の固定部材12のクサビ12b、15dをそれぞれ仮設足場本体2の本体側支柱4のクサビ差し込み部4aに差し込む。さらに、クランプ部材25により仮設足場本体2の本体側支柱4をクランプする。以上のようにして仮設足場用部材10を仮設足場本体2に連結することができる。   Thereafter, as shown in FIG. 3, temporary scaffold members 10 according to the embodiment are connected to both sides in the width direction of the upper portion of the temporary scaffold main body 2. At this time, the wedges 12 b and 15 d of the fixing member 12 of the temporary scaffolding member 10 are respectively inserted into the wedge insertion portions 4 a of the main body side columns 4 of the temporary scaffold main body 2. Furthermore, the main body side support 4 of the temporary scaffold main body 2 is clamped by the clamp member 25. The temporary scaffold member 10 can be connected to the temporary scaffold main body 2 as described above.

次いで、図4に示すように、側部支柱6の下部を仮設足場用部材10の連結部材14に上方から差し込むことによって側部支柱6の下部を連結部材14に連結する。側部支柱6には、床板5aを支持するための床板支持部材7を連結する。床板支持部材7は、上下方向に複数設けることができる。床板支持部材7に床板5aを載置することで作業床5が形成されて張り出し仮設足場3が構築される。   Next, as shown in FIG. 4, the lower portion of the side support 6 is connected to the connection member 14 by inserting the lower portion of the side support 6 from above into the connection member 14 of the temporary scaffolding member 10. A floor plate support member 7 for supporting the floor plate 5a is connected to the side post 6. A plurality of floor board support members 7 can be provided in the vertical direction. By placing the floor plate 5 a on the floor plate supporting member 7, the working floor 5 is formed, and the overhanging temporary scaffold 3 is constructed.

張り出し仮設足場3は、建築物等に合わせて構築することができ、仮設足場本体2の幅方向一方にのみ構築してもよい。   The overhang temporary scaffold 3 can be constructed according to a building etc., and may be constructed only in one width direction of the temporary scaffold main body 2.

(実施形態の作用効果)
以上説明したように、この実施形態によれば、仮設足場用部材10の横部材11を仮設足場本体2の本体側支柱4に連結することで、横部材11が仮設足場本体2から水平方向に延びるように設けられる。この横部材11の先端部の連結部材14には側部支柱6の下部が連結される。側部支柱6には、床板5aを横部材11から上方に離した状態で支持することができる。従って、仮設足場本体2から水平方向に張り出した作業床5を、仮設足場本体2よりも高いところに形成することが可能になるので、例えば高架橋100の補修等を行う際には、仮設足場本体2の幅を拡張することなく、仮設足場用部材10、側部支柱6及び床板5aを使用して側壁部102の外面に対して作業可能な高さの作業床5が容易に得られる。
(Operation and effect of the embodiment)
As described above, according to this embodiment, by connecting the lateral members 11 of the temporary scaffolding member 10 to the main body side columns 4 of the temporary scaffolding main body 2, the lateral members 11 extend horizontally from the temporary scaffolding main body 2. It is provided to extend. The lower portion of the side support 6 is connected to the connecting member 14 at the tip of the cross member 11. The side support 6 can support the floor plate 5 a in a state of being separated upward from the cross member 11. Therefore, since it becomes possible to form work floor 5 projected in the horizontal direction from temporary scaffold main body 2 in a higher place than temporary scaffold main body 2, for example, when repairing elevated bridge 100 etc., temporary scaffold main body A work floor 5 of a height that can be worked on the outer surface of the side wall 102 using the temporary scaffolding member 10, the side struts 6 and the floor plate 5a can be easily obtained without expanding the width of 2.

また、横部材11を構成している固定部材12を仮設足場本体2の本体側支柱4に連結すると、可動部材13の先端部が固定部材12の先端部から突出した状態になり、可動部材13の先端部に側部支柱6の下部が連結部材14を介して連結されることになる。可動部材13は固定部材12に対して水平方向に移動可能に取り付けられているので、可動部材13を移動させることで連結部材6を水平方向に移動させることが可能になる。よって、作業床5の位置の設定自由度が向上する。   Further, when the fixed member 12 constituting the lateral member 11 is connected to the main body side support 4 of the temporary scaffold main body 2, the distal end portion of the movable member 13 protrudes from the distal end portion of the fixed member 12. The lower portion of the side support 6 is connected to the tip of the lower portion through the connection member 14. Since the movable member 13 is mounted to be movable in the horizontal direction with respect to the fixed member 12, moving the movable member 13 enables the connecting member 6 to be moved in the horizontal direction. Therefore, the setting freedom of the position of the work floor 5 is improved.

上述の実施形態はあらゆる点で単なる例示に過ぎず、限定的に解釈してはならない。さらに、特許請求の範囲の均等範囲に属する変形や変更は、全て本発明の範囲内のものである。   The embodiments described above are merely illustrative in every respect and should not be construed as limiting.

However, the present invention is not limited to this. It may be.

また、上記実施形態では、補強部材として第1縦部材22と第2縦部材23を設けているが、これに限らず、強度の要件を満たすのであれば、第1縦部材22と第2縦部材23の一方または両方を省略してもよい。   Moreover, in the said embodiment, although the 1st vertical member 22 and the 2nd vertical member 23 are provided as a reinforcement member, if it satisfy | fills the requirements of not only this but the intensity | strength, the 1st vertical member 22 and the 2nd vertical One or both of the members 23 may be omitted.

本発明は、例えば、各種建築物の建築現場や補修現場、土木作業現場等で構築される仮設足場を構成する仮設足場用部材に関し、特に仮設足場の本体部分から水平方向に張り出すように張り出し仮設足場を構築する場合に使用される仮設足場用部材に関する。   The present invention relates to, for example, a temporary scaffolding member constituting a temporary scaffold constructed at a construction site or a repair site of various buildings, a civil engineering work site or the like, and in particular, overhangs so as to horizontally project from the main body part of the temporary scaffold. The present invention relates to a temporary scaffolding member used when constructing a temporary scaffolding.

一般に、各種建築物の建築現場や補修現場、土木作業現場等では、作業を行うための仮設足場が構築される。仮設足場は、複数の支柱部材、支柱部材を連結する布材やブレース材、梁部材、床板等を組み合わせて構築されている(例えば、特許文献1〜5参照)。   Generally, temporary scaffoldings for working are constructed at construction sites, repair sites, civil engineering work sites, etc. of various buildings. The temporary scaffold is constructed by combining a plurality of support members, a cloth material connecting the support members, a brace material, a beam member, a floor plate, and the like (see, for example, Patent Documents 1 to 5).

特許文献4の仮設足場は、梁部材の長手方向と交差する方向に延び、梁部材から前後方向に突出するように設けられた複数本の根太部材と、複数本の根太部材に渡って掛け渡される床板とを有している。   The temporary scaffold of Patent Document 4 extends over a plurality of joist members provided to extend in a direction intersecting with the longitudinal direction of the beam member and protruding from the joist members in the front-rear direction, and spanning over the plurality joist members And a floor plate to be

特許文献5には、仮設足場本体から水平方向に張り出すように設置される張り出しブラケットが開示されている。張り出しブラケットは、水平部材と、水平部材の基端部に設けられたクサビと、水平部材の先端部に設けられたホゾと、水平部材のホゾ側からクサビ側に向けて下降傾斜した補強材とを備えている。ホゾには上下方向に延びる分岐用支柱が結合されている。クサビが結合される支柱と分岐用支柱と繋ぐように手すりが設けられている。   Patent Document 5 discloses an overhang bracket installed so as to project horizontally from a temporary scaffold main body. The overhanging bracket includes a horizontal member, a wedge provided at the base end of the horizontal member, a flange provided at the distal end of the horizontal member, and a reinforcing member inclined downward from the horizontal side of the horizontal member toward the wedge Is equipped.

ところで、例えば図6に示す高架橋100は、レール等が敷設される橋桁部101と、橋桁部101の側部に設けられた側壁部102とを備えており、この高架橋100を補修等する場合には、一般的に、同図に示すように橋桁部101の下方に仮設足場1を構築することになる。   By the way, for example, the viaduct 100 shown in FIG. 6 includes a bridge girder portion 101 on which rails and the like are laid and a side wall portion 102 provided on the side of the bridge girder portion 101. In general, a temporary scaffold 1 will be constructed below the bridge girder part 101 as shown in the figure.

仮設足場1を橋桁部101の下方に構築することで、橋桁部101の下面の補修等は可能であるが、側壁部102の外面の補修等が問題になる。すなわち、仮設足場1の幅を基礎部分から上部に亘って全体として拡張し、側壁部102の外面に達するような大型の仮設足場にすることで、側壁部102の外面に対する補修等が行えるようになるが、そのような大型の仮設足場を構築するためには多くの資材が必要になるとともに、工数も増大してしまう。また、現場の状態によっては仮設足場の基礎部分の幅を拡張できない場合も想定される。よって、側壁部102については、吊り下げ式の仮設足場等を別途構築しなければならなかった。   By constructing the temporary scaffold 1 below the bridge girder part 101, although repair or the like of the lower surface of the bridge girder part 101 is possible, repair of the outer surface of the side wall part 102 or the like becomes a problem. That is, by making the width of the temporary scaffold 1 as a whole from the base portion to the upper part into a large temporary scaffold that reaches the outer surface of the side wall portion 102, the outer surface of the side wall portion 102 can be repaired. However, in order to construct such a large temporary scaffold, a lot of materials are required, and the number of man-hours also increases. In addition, depending on the condition of the site, it may be assumed that the width of the base portion of the temporary scaffold can not be expanded. Therefore, for the side wall portion 102, a suspended temporary scaffold or the like had to be separately constructed.

ここで、特許文献4では、梁部材から前後方向に突出するように設けられた複数本の根太部材に渡って床板を掛け渡すようにしており、これによって仮設足場本体から水平方向に張り出す作業床を得ることができるようになっている。しかしながら、高架橋100の側壁部102の高さが高い場合には、単に作業床が水平方向に張り出しているだけでは高さが足りないという問題がある。   Here, in Patent Document 4, the floor plate is bridged over a plurality of joist members provided so as to project from the beam member in the front-rear direction, whereby the work of projecting horizontally from the temporary scaffold main body is performed. It is possible to get a floor. However, in the case where the height of the side wall portion 102 of the viaduct 100 is high, there is a problem that the height is not sufficient simply by projecting the working floor in the horizontal direction.

また、特許文献5では、張り出しブラケットを設けることで、仮設足場本体から水平方向に張り出す作業床を得ることができると考えられる。しかしながら、この特許文献5も特許文献4と同様に単に作業床が水平方向に張り出しているだけなので、高さの問題がある。   Moreover, in patent document 5, it is thought that the work floor projected horizontally from a temporary scaffold main body can be obtained by providing an overhang bracket. However, Patent Document 5 also has a problem of height because the work floor merely extends horizontally in the same manner as Patent Document 4.

上述したような問題は高架橋100だけのものではなく、他の建築物の建築現場や補修現場、土木作業現場等でも起こり得る。   The problems as described above are not limited to the viaduct 100, and may occur in other construction sites, repair sites, civil engineering work sites, and the like.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、仮設足場本体から水平方向に張り出した作業床を高いところにも形成できるようにすることにある。   This invention is made in view of this point, The place made as the objective is enabling it to form in the high place also the work floor which extended in the horizontal direction from the temporary scaffold main body.

上記目的を達成するために、本発明では、仮設足場本体から水平方向に延びるように設けられる横部材の先端部に、作業床となる床板を支持する支柱を連結可能にした。   In order to achieve the above object, in the present invention, a support for supporting a floor plate serving as a work floor can be connected to the tip of a horizontal member provided to extend horizontally from a temporary scaffold main body.

第1の発明は、仮設足場を構築する仮設足場用部材において、仮設足場本体を構成する本体側支柱に連結され、該仮設足場本体から水平方向に延びるように設けられる横部材と、上記横部材の先端部に設けられ、作業床となる床板を上記横部材から上方に離して支持可能な側部支柱の下部が連結される連結部とを備え、上記横部材は、上記本体側支柱に連結されて上記仮設足場本体から水平方向に延びる管部材で構成された固定部材と、該固定部材に差し込まれる管部材で構成されるとともに該固定部材に対して水平方向に移動可能に取り付けられ、該固定部材の先端部から突出する可動部材とを備え、上記可動部材における上記固定部材の先端部から突出する部分に上記連結部が固定され、上記固定部材には、上下方向に延びる第1補強部材が固定され、上記第1補強部材の下端部は、上記本体側支柱における上記固定部材の連結部位よりも下方の部位に連結され、上記第1補強部材には、上記固定部材よりも下方に位置付けられるとともに、該固定部材と略平行に延びる下側固定管部材が固定され、上記下側固定管部材に対して水平方向に移動可能に取り付けられ、該下側固定管部材の先端部から突出する下側可動管部材が設けられ、上記下側可動管部材における上記下側固定管部材の先端部から突出する部分に上記連結部が固定されていることを特徴とする。 A first invention relates to a temporary scaffolding member for constructing a temporary scaffolding, a lateral member connected to a main body side post constituting the temporary scaffolding main body and provided to extend horizontally from the temporary scaffolding main body, and the above-mentioned lateral member And a connecting portion to which the lower portion of the side support that can support the floor plate which is provided at the tip end portion of the work floor to be separated upward from the cross member is connected, and the cross member is connected to the main body side support And a fixed member constituted by a tube member extending in the horizontal direction from the temporary scaffold main body, and a tube member inserted into the fixed member, and mounted horizontally movably to the fixed member, A movable member protruding from a distal end of the fixed member, the connecting portion is fixed to a portion of the movable member protruding from the distal end of the fixed member, and the fixed member is a first reinforcing portion extending in the vertical direction Is fixed, the lower end portion of the first reinforcement member is connected to a portion below the connection portion of the fixing member in the main body side column, and is positioned lower than the fixing member in the first reinforcement member And a lower fixed tube member extending substantially parallel to the fixed member is fixed, horizontally movably attached to the lower fixed tube member, and protrudes from a tip end of the lower fixed tube member.

(仮設足場用部材10の構成)
図1及び図2に示すように、仮設足場用部材10は、横部材11と、連結部材(連結部)14と、第1補強部材15と、下側固定管部材16と、下側可動管部材17と、雄ネジ部材18と、第2補強部材20と、クランプ部材21と、第1縦部材22と、第2縦部材23とを備えている。
(Configuration of temporary scaffolding member 10)
As shown in FIGS. 1 and 2, the temporary scaffolding member 10 includes a lateral member 11, a connecting member (connecting portion) 14, a first reinforcing member 15, a lower fixed tube member 16, and a lower movable tube. A member 17, a male screw member 18, a second reinforcing member 20, a clamp member 21, a first longitudinal member 22 and a second longitudinal member 23 are provided.

図5等に示すように、横部材11は、仮設足場本体2を構成する本体側支柱4に連結され、該仮設足場本体2から水平方向に延びるように設けられる部材である。すなわち、横部材11は、本体側支柱4に連結されて仮設足場本体2から水平方向に突出するように延びる固定部材12と、該固定部材12に対して水平方向に移動可能に取り付けられ、該固定部材12の先端部から突出する可動部材13とを備えている。   As shown in FIG. 5 etc., the lateral member 11 is a member that is connected to the main body side support 4 that constitutes the temporary scaffold main body 2 and extends from the temporary scaffold main body 2 in the horizontal direction. That is, the horizontal member 11 is attached to the fixing member 12 so as to be movable in the horizontal direction with respect to the fixing member 12, the fixing member 12 being connected to the main body side column 4 and extending horizontally from the temporary scaffold main body 2. And a movable member 13 projecting from the tip of the fixed member 12.

固定部材12は、仮設足場本体2から水平方向に延びる鋼管からなる管部材で構成されている。固定部材12の先端部(図1における右端部)の下側には、ネジ孔を有するナット12aが下方へ突出するように固定されている。このナット12aのネジ孔には、雄ネジ部材18が螺合するようになっている。固定部材12の先端部の周壁部には、ナット12aのネジ孔と連通する貫通孔(図示せず)が該周壁部を貫通するように形成されており、ナット12aのネジ孔に螺合した雄ネジ部材18の先端部が貫通孔を通って固定部材12の内部へ突出可能に構成されている。   The fixing member 12 is formed of a pipe member made of a steel pipe extending in the horizontal direction from the temporary scaffold main body 2. A nut 12a having a screw hole is fixed to the lower side of the tip end portion (right end portion in FIG. 1) of the fixing member 12 so as to project downward. A male screw member 18 is screwed into the screw hole of the nut 12a. A through hole (not shown) communicating with the screw hole of the nut 12a is formed in the peripheral wall of the distal end of the fixing member 12 so as to penetrate the peripheral wall and screwed into the screw hole of the nut 12a The tip end of the male screw member 18 is configured to be able to project into the interior of the fixing member 12 through the through hole.

固定部材12の基端部(図1における左端部)における下側には、クサビ12bが下方へ突出するように固定されている。このクサビ12bは、本体側支柱4のクサビ差し込み部4aに上方から差し込まれた状態で係合するようになっている。また、固定部材12におけるナット12aとクサビ12bとの間には、金属製の板材からなるブラケット12cが下方へ突出するように設けられている。ブラケット12cは、クサビ12bに接近して設けられている。   A wedge 12b is fixed to the lower side of the proximal end (left end in FIG. 1) of the fixing member 12 so as to project downward. The wedge 12 b is engaged with the wedge insertion portion 4 a of the main body side support 4 while being inserted from above. Further, a bracket 12c made of a metal plate material is provided between the nut 12a and the wedge 12b in the fixing member 12 so as to project downward. The bracket 12c is provided close to the wedge 12b.

可動部材13は、鋼管からなる管部材で構成されている。可動部材13の外径は、固定部材12の内径よりも小さく設定されており、固定部材12の内部に差し込むことが可能に形成されている。可動部材13の長さは、固定部材12の長さよりも短く設定されている。可動部材13は、固定部材12に差し込んだ状態で該固定部材12の中心線方向(水平方向)に相対的に移動させることができるようになっており、図1に示すように可動部材13を進出させた状態から、図2に示すように可動部材13を後退させた状態、また可動部材13を後退させた状態から、進出させた状態にすることができる。   The movable member 13 is constituted by a pipe member made of a steel pipe. The outer diameter of the movable member 13 is set to be smaller than the inner diameter of the fixed member 12 and can be inserted into the fixed member 12. The length of the movable member 13 is set shorter than the length of the fixed member 12. The movable member 13 can be relatively moved in the center line direction (horizontal direction) of the fixed member 12 in a state of being inserted into the fixed member 12, and as shown in FIG. From the advanced state, as shown in FIG. 2, the movable member 13 can be moved backward, or the movable member 13 can be moved backward from the retracted state.

可動部材13は、進出させた状態と後退させた状態との間の任意の位置で停止させることができる。図1に示す可動部材13を進出させた状態では、横部材11の長さが1500mm〜2000mmの間となるように、固定部材12及び可動部材13の長さを設定することができる。また、図2に示す可動部材13を後退させた状態では、横部材11の長さが800mm〜1500mmの間となるように、固定部材12及び可動部材13の長さを設定することができる。   The movable member 13 can be stopped at any position between the advanced state and the retracted state. In the state in which the movable member 13 shown in FIG. 1 is advanced, the lengths of the fixed member 12 and the movable member 13 can be set such that the length of the horizontal member 11 is between 1500 mm and 2000 mm. Further, in a state in which the movable member 13 shown in FIG. 2 is retracted, the lengths of the fixed member 12 and the movable member 13 can be set so that the length of the horizontal member 11 is between 800 mm and 1500 mm.

雄ネジ部材18は、可動部材13が固定部材12に対して水平方向に移動するのを阻止するための阻止部材である。この雄ネジ部材18は、固定部材12に固定されたナット12aのネジ孔に螺合させて時計回りに回転させると固定部材12の内部へ進出する一方、反時計周りに回転させると後退する。つまり、雄ネジ部材18は、固定部材12に設けられたネジ孔に螺合することによって進退動作する。   The male screw member 18 is a blocking member for blocking the movable member 13 from moving in the horizontal direction with respect to the fixed member 12. The male screw member 18 is screwed into the screw hole of the nut 12a fixed to the fixing member 12 and is rotated clockwise, and advances into the inside of the fixing member 12, while it is retracted when it is rotated counterclockwise. That is, the male screw member 18 advances and retracts by being screwed into a screw hole provided in the fixing member 12.

雄ネジ部材18が進出すると、固定部材12の貫通孔を通って固定部材12の内部へ突出するので、雄ネジ部18の先端部が、固定部材12の内部に差し込まれている可動部材13の外面に当接し、更に雄ネジ部材18を締め込むことで可動部材13の水平方向の移動を雄ネジ部18によって阻止することができる。一方、雄ネジ部材18が後退した状態では、雄ネジ部18の先端部が、固定部材12の内部に差し込まれている可動部材13の外面から離れるので、該可動部材13の水平方向の移動を許容することになる。従って、雄ネジ部18を緩めることで可動部材13を固定部材12に対して水平方向に移動させて横部材11の長さを無段階に変更することができ、横部材11が所望の長さになった時に雄ネジ部18を締め込むことで可動部材13が固定部材12に固定されて横部材11の長さが所望の長さから変化しないように、長さを維持することができる。   When the male screw member 18 is advanced, the male screw member 18 protrudes through the through hole of the fixed member 12 into the inside of the fixed member 12, so that the tip of the male screw 18 is inserted into the inside of the fixed member 12. The horizontal movement of the movable member 13 can be blocked by the male screw 18 by abutting on the outer surface and further tightening the male screw 18. On the other hand, in the state where the male screw member 18 is retracted, the distal end of the male screw 18 separates from the outer surface of the movable member 13 inserted into the inside of the fixed member 12. It will be acceptable. Therefore, by loosening the male screw portion 18, the movable member 13 can be moved horizontally with respect to the fixed member 12 to change the length of the cross member 11 steplessly, and the cross member 11 has a desired length. By tightening the male screw portion 18 when it comes to a fixed length, the movable member 13 can be fixed to the fixed member 12 and the length can be maintained so that the length of the cross member 11 does not change from the desired length.

固定部材12のブラケット12cの下部には、上下方向に延びる傾斜部材24の上端部が連結されている。傾斜部材24の下部は、固定部材12の基端部から下方に離れている。この傾斜部材24の下部には、クランプ部材25が連結されている。クランプ部材25は、仮設足場本体2の本体側支柱4を径方向に挟持する(クランプする)ように構成された周知の部材である。   The lower end of the bracket 12 c of the fixing member 12 is connected to an upper end portion of an inclined member 24 extending in the vertical direction. The lower portion of the inclined member 24 is spaced downward from the proximal end of the fixing member 12. The clamp member 25 is connected to the lower portion of the inclined member 24. The clamp member 25 is a known member configured to clamp (clamp) the main body side support column 4 of the temporary scaffold main body 2 in the radial direction.

連結部材14は、横部材11の先端部、即ち、可動部材13における固定部材12の先端部から突出する部分に固定されている。連結部材14には、図4に示すように作業床5となる床板5aを横部材11から上方に離して支持可能な側部支柱6の下部が連結される。連結部材14は、上下方向に延びる鋼管からなる管部材で構成されている。連結部材14の内径は、側部支柱6の外径よりも若干小さく設定されており、側部支柱6の下部を連結部材14に差し込むことにより、側部支柱6の下部を連結部材14に連結することができるようになっている。   The connecting member 14 is fixed to the end of the cross member 11, that is, the portion of the movable member 13 that protrudes from the end of the fixed member 12. As shown in FIG. 4, the lower portion of the side support 6 capable of supporting the floor plate 5 a serving as the work floor 5 upward from the cross member 11 is connected to the connecting member 14. The connection member 14 is formed of a pipe member made of a steel pipe extending in the vertical direction. The inner diameter of the connecting member 14 is set to be slightly smaller than the outer diameter of the side support 6, and the lower portion of the side support 6 is connected to the connecting member 14 by inserting the lower portion of the side support 6 into the connecting member 14. It can be done.

連結部材14の上部には、上側接続管部14aが横部材11側へ向けて水平方向に突出するように固定されている。上側接続管部14aの内径は、可動部材13の外径よりも若干大きく設定されており、可動部材13の先端部を上側接続管部14aに差し込むことができるようになっている。可動部材13の先端部は、上側接続管部14aに差し込まれた状態で溶接や締結部材等によって固定されている。また、連結部材14における上側接続管部14aから下方に離れた部位には、下側接続管部14bが上側接続管部14aと同方向に突出するように固定されている。さらに、連結部材14の下部には、突出板部14cが下方へ突出するように設けられている。   An upper connection pipe portion 14 a is fixed to an upper portion of the connection member 14 so as to horizontally project toward the cross member 11 side. The inner diameter of the upper connection pipe portion 14a is set to be slightly larger than the outer diameter of the movable member 13, and the tip end portion of the movable member 13 can be inserted into the upper connection pipe portion 14a. The distal end portion of the movable member 13 is fixed by welding, a fastening member or the like in a state of being inserted into the upper connection pipe portion 14a. Further, the lower connection pipe portion 14 b is fixed to a portion of the connection member 14 which is separated downward from the upper connection pipe portion 14 a so as to project in the same direction as the upper connection pipe portion 14 a. Further, a projecting plate portion 14 c is provided at the lower part of the connecting member 14 so as to project downward.

第1補強部材15は上下方向に延びており、上側へ行くほど固定部材12の先端部に近づくように傾斜している。第1補強部材15は鋼管で構成されている。第1補強部材15の上部は、略鉛直に延びる鉛直部15aで構成されており、この鉛直部15aも鋼管である。鉛直部15aの上端部は、固定部材12の先端側においてナット12aよりも基端寄りの部位に固定されている。これにより、第1補強部材15の上端部が固定部材12に固定されることになる。   The first reinforcing member 15 extends in the vertical direction, and is inclined so as to approach the tip of the fixing member 12 as it goes upward. The first reinforcing member 15 is formed of a steel pipe. The upper portion of the first reinforcing member 15 is formed of a vertical portion 15a extending substantially vertically, and the vertical portion 15a is also a steel pipe. The upper end portion of the vertical portion 15 a is fixed at a position closer to the base end than the nut 12 a on the tip end side of the fixing member 12. As a result, the upper end portion of the first reinforcing member 15 is fixed to the fixing member 12.

第1補強部材15の下端部は、本体側支柱4における固定部材12の連結部位よりも下方の部位に連結されるようになっている。すなわち、第1補強部材15の下端部は固定部材12の基端部よりも下方に位置しており、この第1補強部材15の下端部には連結板部15bが設けられている。連結板部15bは上下方向に延びていて、その上端部が第1補強部材15の下端部に対して溶接等の固定方法によって固定されている。連結板部15bの下部には、本体側支柱4のクサビ差し込み部4aに差し込まれるクサビ15dが固定されている。クサビ15dと、クサビ12bとは、上下方向に延びる同一直線上に位置するように配置される。また、連結板部15bの上部には、本体側支柱4に対して側方から当接する当接部15cが設けられている。   The lower end portion of the first reinforcing member 15 is connected to a portion below the connection portion of the fixing member 12 in the main body side support 4. That is, the lower end portion of the first reinforcing member 15 is located below the base end portion of the fixing member 12, and the connecting plate portion 15 b is provided at the lower end portion of the first reinforcing member 15. The connecting plate portion 15 b extends in the vertical direction, and the upper end portion thereof is fixed to the lower end portion of the first reinforcing member 15 by a fixing method such as welding. The wedge 15 d to be inserted into the wedge insertion portion 4 a of the main body side support 4 is fixed to the lower portion of the connection plate portion 15 b. The wedge 15 d and the wedge 12 b are disposed on the same straight line extending in the vertical direction. Further, on the upper portion of the connection plate portion 15b, a contact portion 15c that contacts the main body side support 4 from the side is provided.

第1補強部材15には、固定部材12よりも下方に位置付けられるとともに、該固定部材12と略平行に延びる下側固定管部材16が固定されている。下側固定管部材16は、鋼管で構成されている。下側固定管部材16の中心線方向中央部よりも先端側(図1における右側)寄りの部位が、第1補強部材15における鉛直部15aの下端部に固定されている。   A lower fixed tube member 16 which is positioned below the fixed member 12 and extends substantially in parallel with the fixed member 12 is fixed to the first reinforcing member 15. The lower fixed pipe member 16 is formed of a steel pipe. A portion closer to the tip end side (right side in FIG. 1) than the central portion of the lower fixed tube member 16 in the center line direction is fixed to the lower end portion of the vertical portion 15 a of the first reinforcing member 15.

下側固定管部材16には、水平方向に延びる鋼管からなる下側可動管部材17が取り付けられている。下側可動管部材17の外径は、下側固定管部材16の内径よりも若干小さく設定されており、下側可動管部材17を下側固定管部材16に差し込んだ状態で中心線方向に相対的に移動させることが可能になっている。つまり、下側可動管部材17は、下側固定管部材16に対して水平方向に移動可能に取り付けられている。   A lower movable pipe member 17 made of a steel pipe extending in the horizontal direction is attached to the lower fixed pipe member 16. The outer diameter of the lower movable tube member 17 is set to be slightly smaller than the inner diameter of the lower fixed tube member 16, and in the direction of the center line with the lower movable tube member 17 inserted in the lower fixed tube member 16. It is possible to move relatively. That is, the lower movable pipe member 17 is mounted movably in the horizontal direction with respect to the lower fixed pipe member 16.

下側可動管部材17の長さは、下側固定管部材16に差し込んだ状態で該下側固定管部材16の先端部から突出するように設定されている。下側可動管部材17における下側固定管部材16の先端部から突出する部分に連結部材14が固定されている。すなわち、下側可動管部材17の外径は、連結部材14の下側接続管部14bの内径よりも若干小さく設定されており、下側可動管部材17における下側固定管部材16の先端部から突出する部分を連結部材14の下側接続管部14bに差し込むことができるようになっている。下側可動管部材17における下側固定管部材16の先端部から突出する部分は、下側接続管部14bに差し込まれた状態で溶接や締結部材等によって固定されている。従って、連結部材14における可動部材13の固定部位よりも下方の部位に下側可動管部材17が固定されることになる。   The length of the lower movable tube member 17 is set to project from the tip of the lower fixed tube member 16 in a state of being inserted into the lower fixed tube member 16. The connecting member 14 is fixed to a portion of the lower movable pipe member 17 that protrudes from the tip of the lower fixed pipe member 16. That is, the outer diameter of the lower movable pipe member 17 is set to be slightly smaller than the inner diameter of the lower connection pipe portion 14 b of the connection member 14, and the tip of the lower fixed pipe member 16 in the lower movable pipe member 17 The part which protrudes from can be inserted in the lower connection pipe part 14b of the connection member 14. As shown in FIG. The portion of the lower movable pipe member 17 that protrudes from the tip end of the lower fixed pipe member 16 is fixed by welding, a fastening member, or the like in a state of being inserted into the lower connection pipe portion 14b. Therefore, the lower movable tube member 17 is fixed to a portion of the connecting member 14 below the fixed portion of the movable member 13.

第2補強部材20は、上下方向に延びる金属製の棒材や管材等からなるものである。第2補強部材20の上端部は、連結部材14の突出板部14cに対して水平方向に延びる軸20a周りに揺動可能に連結されている。軸20aは、第2補強部材20の上端部を支持し、かつ、第2補強部材20の下端部が第1補強部材15に接離するように、第2補強部材20を揺動させる揺動軸となる部材である。   The second reinforcing member 20 is made of a metal bar or pipe extending in the vertical direction. The upper end portion of the second reinforcing member 20 is swingably connected around an axis 20 a extending in the horizontal direction with respect to the protruding plate portion 14 c of the connecting member 14. The shaft 20a supports the upper end portion of the second reinforcing member 20, and swings the second reinforcing member 20 so that the lower end portion of the second reinforcing member 20 contacts and separates from the first reinforcing member 15. It is a member which becomes an axis.

第2補強部材20の下端部には、第1補強部材15をクランプするためのクランプ部材21が水平方向に延びる軸20b周りに揺動可能に連結されている。軸20bの延びる方向は軸20aの延びる方向と一致している。クランプ部材21は、第1補強部材15を径方向に挟持する(クランプする)ように構成された周知の部材である。   At the lower end portion of the second reinforcing member 20, a clamp member 21 for clamping the first reinforcing member 15 is swingably connected around an axis 20b extending in the horizontal direction. The extending direction of the shaft 20b coincides with the extending direction of the shaft 20a. The clamp member 21 is a known member configured to clamp (clamp) the first reinforcing member 15 in the radial direction.

図1に示す可動部材13を進出させた状態では、可動部材13に下側可動管部材17が連結部材14を介して連結されているので、下側可動管部材17も進出することになる。また、このとき、第2補強部材20の上端部が可動部材13に連結部材14を介して連結されているので、第2補強部材20の上端部も同様に進出することになる。第2補強部材20の上端部が進出すると、第2補強部材20が揺動して該第2補強部材20の下端部が上昇することになる。この上昇位置でクランプ部材21により第1補強部材15をクランプすると、第2補強部材20により連結部材14を下方から支持することができるとともに、連結部材14の傾きを抑制することができる。また、第2補強部材20の水平面に対する傾斜角度は、第1補強部材15の水平面に対する傾斜角度よりも緩やかになっている。   In the state in which the movable member 13 shown in FIG. 1 is advanced, since the lower movable pipe member 17 is connected to the movable member 13 via the connecting member 14, the lower movable pipe member 17 is also advanced. At this time, since the upper end portion of the second reinforcing member 20 is connected to the movable member 13 via the connecting member 14, the upper end portion of the second reinforcing member 20 also advances. When the upper end portion of the second reinforcing member 20 advances, the second reinforcing member 20 swings and the lower end portion of the second reinforcing member 20 is lifted. When the first reinforcing member 15 is clamped by the clamp member 21 at the raised position, the connecting member 14 can be supported from below by the second reinforcing member 20, and the inclination of the connecting member 14 can be suppressed. Further, the inclination angle of the second reinforcing member 20 with respect to the horizontal plane is gentler than the inclination angle of the first reinforcing member 15 with respect to the horizontal plane.

図2に示す可動部材13を後退させた状態では、下側可動管部材17も後退し、第2補強部材20の上端部も後退する。第2補強部材20の上端部が後退すると、第2補強部材20が揺動して該第2補強部材20の下端部が下降することになる。この下降位置でクランプ部材21により第1補強部材15をクランプすると、第2補強部材20により連結部材14を下方から支持することができるとともに、連結部材14の傾きを抑制することができる。クランプ部材21による第1補強部材15のクランプ位置は、第2補強部材20の揺動角度に応じて無段階で変更することができる。   In the state where the movable member 13 shown in FIG. 2 is retracted, the lower movable pipe member 17 is also retracted, and the upper end portion of the second reinforcing member 20 is also retracted. When the upper end portion of the second reinforcing member 20 retracts, the second reinforcing member 20 swings and the lower end portion of the second reinforcing member 20 is lowered. When the first reinforcing member 15 is clamped by the clamp member 21 at the lowered position, the connecting member 14 can be supported from below by the second reinforcing member 20, and the inclination of the connecting member 14 can be suppressed. The clamp position of the first reinforcing member 15 by the clamp member 21 can be changed steplessly according to the swing angle of the second reinforcing member 20.

第1縦部材22は上下方向に延びる金属製の棒材や管材等からなるものである。第1縦部材22の上端部は、固定部材12における鉛直部15aの固定部位よりも基端寄りの部位に固定されている。第1縦部材22の下端部は、第1補強部材15におけるクランプ部材21によるクランプ位置(上昇端位置)よりも上側の部位に固定されている。また、第1縦部材22の上下方向中間部には、下側固定管部材16の基端部が固定されている。従って、第1縦部材22によって固定部材12と第1補強部材15を連結することができるとともに、固定部材12と下側固定管部材16、下側固定管部材16と第1補強部材15を連結することもできる。   The first vertical member 22 is made of a metal bar or pipe extending in the vertical direction. The upper end portion of the first vertical member 22 is fixed to a portion closer to the proximal end than the fixing portion of the vertical portion 15 a in the fixing member 12. The lower end portion of the first vertical member 22 is fixed at a position above the clamping position (rising end position) of the first reinforcing member 15 by the clamp member 21. Further, a base end portion of the lower fixed tube member 16 is fixed to a vertically middle portion of the first vertical member 22. Therefore, while being able to connect fixed member 12 and the 1st reinforcement member 15 by the 1st vertical member 22, fixed member 12 and lower fixed tube member 16, lower fixed tube member 16 and 1st reinforcement member 15 are connected. You can also

第2縦部材23は上下方向に延びる金属製の棒材や管材等からなるものである。第2縦部材23の上端部は、固定部材12における第1縦部材22の固定部位よりも基端寄りの部位に固定されている。第2縦部材23の下端部は、第1補強部材15におけるクランプ部材21によるクランプ位置(図2に示す下降端位置)よりも下側の部位に固定されている。従って、第2縦部材23によって固定部材12と第1補強部材15を連結することができる。また、第1補強部材15におけるクランプ部材21によるクランプ位置は、上昇端位置であっても下降端位置であっても、第1縦部材22と第2縦部材23との間に設定される。   The second vertical member 23 is made of a metal rod or pipe extending in the vertical direction. The upper end portion of the second vertical member 23 is fixed to a portion closer to the proximal end than the fixing portion of the first vertical member 22 in the fixing member 12. The lower end portion of the second vertical member 23 is fixed at a lower position than the clamp position (the lowering end position shown in FIG. 2) by the clamp member 21 in the first reinforcing member 15. Therefore, the fixing member 12 and the first reinforcing member 15 can be connected by the second vertical member 23. Further, the clamp position of the first reinforcement member 15 by the clamp member 21 is set between the first longitudinal member 22 and the second longitudinal member 23 regardless of whether it is the rising end position or the falling end position.

(仮設足場の構築)
次に、上記のように構成された仮設足場用部材10を使用して仮設足場を構築する場合について説明する。まず、図6に示すように橋桁部101の下方に仮設足場本体2を構築する。また、実施形態に係る仮設足場用部材10の連結部材14の水平方向の位置を所望の位置にしておく。このとき、雄ネジ部材18を緩めておくとともに、クランプ部材21を非クランプ状態としておく。これにより、可動部材13及び下側可動管部材17を水平方向に移動させることができるとともに、可動部材13及び下側可動管部材17の水平方向の移動に連動させて第2補強部材20を揺動させることができる。連結部材14の水平方向の位置を所望の位置にした後、雄ネジ部材18を締め込むとともに、クランプ部材21をクランプ状態にすることで連結部材14が固定される。連結部材14の位置は、作業床5を、高架橋100の側壁部102から外側に離した所に形成することができるように設定する。

Further, the horizontal position of the connection member 14 of the temporary scaffolding member 10 according to the embodiment is set to a desired position. At this time, the male screw member 18 is loosened and the clamp member 21 is unclamped. Thereby, the movable member 13 and the lower movable pipe member 17 can be moved in the horizontal direction, and the second reinforcing member 20 is shaken in conjunction with the horizontal movement of the movable member 13 and the lower movable pipe member 17. It can be moved. After setting the horizontal position of the connecting member 14 to a desired position, the connecting member 14 is fixed by tightening the male screw member 18 and putting the clamp member 21 in a clamping state. The position of the connecting member 14 is set such that the working floor 5 can be formed at a position away from the side wall portion 102 of the viaduct 100.

その後、図3に示すように、仮設足場本体2の上部における幅方向両側にそれぞれ実施形態に係る仮設足場用部材10を連結する。このとき、仮設足場用部材10の固定部材12のクサビ12b、15dをそれぞれ仮設足場本体2の本体側支柱4のクサビ差し込み部4aに差し込む。さらに、クランプ部材25により仮設足場本体2の本体側支柱4をクランプする。以上のようにして仮設足場用部材10を仮設足場本体2に連結することができる。   Thereafter, as shown in FIG. 3, temporary scaffold members 10 according to the embodiment are connected to both sides in the width direction of the upper portion of the temporary scaffold main body 2. At this time, the wedges 12 b and 15 d of the fixing member 12 of the temporary scaffolding member 10 are respectively inserted into the wedge insertion portions 4 a of the main body side columns 4 of the temporary scaffold main body 2. Furthermore, the main body side support 4 of the temporary scaffold main body 2 is clamped by the clamp member 25. The temporary scaffold member 10 can be connected to the temporary scaffold main body 2 as described above.

次いで、図4に示すように、側部支柱6の下部を仮設足場用部材10の連結部材14に上方から差し込むことによって側部支柱6の下部を連結部材14に連結する。側部支柱6には、床板5aを支持するための床板支持部材7を連結する。床板支持部材7は、上下方向に複数設けることができる。床板支持部材7に床板5aを載置することで作業床5が形成されて張り出し仮設足場3が構築される。   Next, as shown in FIG. 4, the lower portion of the side support 6 is connected to the connection member 14 by inserting the lower portion of the side support 6 from above into the connection member 14 of the temporary scaffolding member 10. A floor plate support member 7 for supporting the floor plate 5a is connected to the side post 6. A plurality of floor board support members 7 can be provided in the vertical direction. By placing the floor plate 5 a on the floor plate supporting member 7, the working floor 5 is formed, and the overhanging temporary scaffold 3 is constructed.

張り出し仮設足場3は、建築物等に合わせて構築することができ、仮設足場本体2の幅方向一方にのみ構築してもよい。   The overhang temporary scaffold 3 can be constructed according to a building etc., and may be constructed only in one width direction of the temporary scaffold main body 2.

(実施形態の作用効果)
以上説明したように、この実施形態によれば、仮設足場用部材10の横部材11を仮設足場本体2の本体側支柱4に連結することで、横部材11が仮設足場本体2から水平方向に延びるように設けられる。この横部材11の先端部の連結部材14には側部支柱6の下部が連結される。側部支柱6には、床板5aを横部材11から上方に離した状態で支持することができる。従って、仮設足場本体2から水平方向に張り出した作業床5を、仮設足場本体2よりも高いところに形成することが可能になるので、例えば高架橋100の補修等を行う際には、仮設足場本体2の幅を拡張することなく、仮設足場用部材10、側部支柱6及び床板5aを使用して側壁部102の外面に対して作業可能な高さの作業床5が容易に得られる。
